java在EntityManagerFactory配置中未指定PersistenceProvider

Question

我正在应用程序中使用Spring+JPA+Hibernate。Jetty web服务器启动时（初始化期间），我面临以下问题

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor#0': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [commonApplicationContext.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: No PersistenceProvider specified in EntityManagerFactory configuration, and chosen PersistenceUnitInfo does not specify a provider class name either

我的配置文件如下

公共应用程序上下文。xml-->

<context:component-scan base-package="com.test.common.dao.*" />

    <context:annotation-config />

    <!--tx:annotation-driven transaction-manager="defaultTransactionManager"/-->

    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="persistenceUnitName" value="common"/>
        <property name="persistenceXmlLocation" value="classpath:META-INF/persistence.xml" />
        <property name="packagesToScan" value="com.test.common.dao.entity"/>
    </bean>

    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory"/>
    </bean>

    <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/>

持久性。xml-->
